Definitions
- the present invention relates generally to molded, non-metallic, self-retaining bushings; and, more particularly, to improved self-retaining bushings molded from a deformable, resilient, thermoplastic material and which are suitable for usage in a wide range of diverse applications--especially, applications which require adherence to close tolerance inside and outside diameters--viz., tolerances on the order of ⁇ 0.005" and, in many instances, on the order of only ⁇ 0.002"--and/or have stringent requirements in terms of sound and/or shock absorbency characteristics. More specifically, the present invention comprises a significant improvement to self-retaining grommets of the type disclosed in U.S. Pat. No. 3,099,057.
- self-retaining grommets and similar devices of the type disclosed in the aforesaid U.S. Pat. No. 3,099,057 employ a tubular body portion molded from a suitable thermoplastic material (such, for example, as nylon) with the body portion having an enlarged retaining head at one end and an upsettable, resilient, deformable, flip portion at its opposite extremity which is designed to be expanded outwardly by means of appropriate standard expansion-type tooling inserted into the tubular body portion.
- a suitable thermoplastic material such, for example, as nylon
- the outwardly expanded deformable extremity is caused to flip outwardly and backwardly upon the tubular body about a weakened annular area of reduced wall thickness defined by a groove formed interiorly in the tubular body portion so as to form a second enlarged retaining head disposed on the device and spaced axially from the first integral enlarged retaining head by an axial distance equal to the thickness of the component(s) through which the device is inserted.
- a further and more detailed object of the invention is the provision of a unitary, molded, self-retaining bushing which, because of its unique configuration, facilitates blind installation of the bushing into difficult-to-reach locations and, at the same time, facilitates insertion of suitable standard expanding tooling into the bushing interior for setting such bushing in a desired permanent location.
- An ancillary object of the invention is the provision of an improved self-retaining bushing of the molded, unitary, deformable type which readily permits use of any desired amount of thermoplastic material and of any desired wall thickness for maximizing either or both of the sound absorbency and/or shock absorbency characteristics of the bushing; yet, wherein such additional material and increased wall thickness do not impede or otherwise deleteriously affect either the flexibility of the expandable flip end of the bushing or free access to the bushing interior by required standard expansion-type tooling used to "set" the bushing in place.
- FIG. 1 is a cross-sectional view taken longitudinally through a conventional grommet of the type described in the aforesaid U.S. Pat. No. 3,099,057, here illustrating particularly, in exaggerated form for purposes of clarity, the outwardly flared extremity of the expandable end of the grommet which is inherently formed in the molding process;
- FIG. 2 is a cross-sectional view similar to FIG. 1, but here illustrating the conventional self-retaining grommet during an initial step in its installation in a sheet-like structural component and depicting particularly the need to provide an oversized opening in the structural component sized to readily receive the outwardly flared extremity of the grommet;
- FIG. 3 is a cross-sectional view taken longitudinally through an improved deformable close tolerance bushing embodying features of the present invention
- FIG. 4 is a cross-sectional view similar to FIG. 2, but are illustrating the close tolerance bushing of the present invention during the initial stages of its installation in a sheet-like structural component and illustrating also, in phantom, conventional tooling of the type that can be used to set the bushing in place;
- FIG. 5 is a view similar to FIG. 4, but here illustrating the close tolerance bushing of the present invention following setting thereof with the formable extremity of the tubular body portion having been expanded outwardly and having been flipped backwardly upon itself so as to securely affix the bushing in place within the hole passing through the structural member;
- FIG. 6 is a view similar to FIG. 5 but with the expanding tooling removed, here illustrating a slightly modified form of the invention particularly suitable for use in applications where there is a need for providing increased shock and/or sound absorbing characteristics in the bushing.
- FIG. 1 there has been illustrated a conventional, commercially available, molded thermoplastic self-retaining grommet, generally indicted at 10, of the type generally disclosed in the aforesaid U.S. Pat. No. 3,099,057.
- a conventional, commercially available, molded thermoplastic self-retaining grommet generally indicted at 10, of the type generally disclosed in the aforesaid U.S. Pat. No. 3,099,057.
- Such a device comprises a generally tubular body portion 11 having an outside diameter D 1 , a premolded enlarged retaining head 12 at one extremity (the righthand extremity as viewed in the drawing), and an axially extending flexible flip portion 14 of reduced wall thickness at its opposite extremity.
- FIG. 1 In the aforesaid U.S. Pat. No. 3,099,057, such a device is illustrated in FIG. 1 and is described in the specification as a grommet having a tubular body portion " . . . preferably of a
- a core pin (not shown) having a raised annular ridge must be positioned within the mold for forming an annular groove 15 at the junction between the main tubular body portion 11 and the axially extending flip extemity 14 of reduced wall thickness so as to form an annular weakened area 16 about which the deformable flip portion 14 can be expanded and flipped when the grommet is installed.
- Such a core pin must then be removed prior to complete setting of the heated thermoplastic material--and, this operation inherently produces a flared extremity 18 having an outside diameter D 2 greater than the outside diameter D 1 of the main tubular body portion 11.
- the diameter D 2 of the flared extremity 18 has been commonly found to range between 0.004" to 0.006" greater than the diameter D 1 of the main tubular body portion 11 and, in general, the flared extremity has been found to be close to the upper end of that range. Consequently, when assembled within a structural component 19 having a fastener-receiving opening 20 with a diameter D 3 equal to or greater than D 2 , there is a relatively loose radial fit between the main tubular body portion 11 and the structural component 19. As a result, the fastening device 10, even when tightly crimped in place axially, is free to move radially and such motion tends to produce undesired wear which gradually further loosens the device.
- the outwardly flared extremity becomes an inwardly flared extremity which engages the outer surface of the main tubular body portion of the bushing and aids in maintaining the flip portion 14 of the bushing in a somewhat stand-off position from the main tubular body 11, thereby forming a second enlarged retaining head which coacts with the first enlarged retaining head to preclude axial motion of the bushing.
- stepped shoulder 22 which is formed on and surrounds the main tubular body portion 11 and extends axially from the premolded enlarged head 12 towards, but terminates short of, the weakened area 16 defined by the internal groove 15.
- the stepped shoulder 22 has an outer diameter D 3 at least equal to and, preferably greater than, the outer diameter D 2 of the outwardly flared extremity 18 on the flip portion 14 of the bushing.
- the bushing 21 is inserted into an opening or hole 20 formed in a stiffener or similar structural component 19 with the premolded enlarged head 12 being seated against one wall of the structural component 19 (the righthand wall 19R as viewed in FIG. 4).
- the stepped shoulder 22 of the exemplary bushing 21 has an external diameter equal to that of the flared extremity 18 and essentially equal to the diameter of the hole 20 in the structural component 19; although, preferably, the stepped shoulder has a somewhat greater external diameter than the flared extremity 18. In either case, while the flared extremity 18 is free to pass through the hole 20, the stepped shoulder 22 fits snugly within the hole and precludes radial movement of the bushing 21 within the hole.
- the axial length of the stepped shoulder 22 is not critical to the present invention and may vary dependent upon the thickness of the structural component(s) into which the device is to be inserted.
- the axial length of the stepped shoulder 22 will desirably approach the thickness of the structural component; whereas when used with relatively thick components, it is only necessary that the shoulder 22 have a sufficient axial length as to provide a good close tolerance bearing surface.
- the outwardly flared extremity 18 which, because of the slight flare, presents a tapered or somewhat frusto-conical lead-in portion 24 at its leading end as the bushing is inserted into the hole 20.
- Such facilitated lead-in is, of course, further improved where the hole 20 and shoulder 22 are slightly larger than the flared extremity 18.
- the stepped shoulder 22 is preferably provided with a rounded radius of curvature at its inboard end as indicated at 25 which serves to facilitate insertion of the shoulder into the opening 20.
- the flared extremity 18 is futher highly advantageous in that it facilitates insertion of standard expansion-type tooling into the interior of the bushing 21 for the purpose of permanently securing the bushing in place.
- an anvil or similar support tool 26 is positioned against the premolded enlarged head 12 of the bushing while a tapered expanding tool 28 is moved axially (to the right as viewed in the drawing) into the flared extremity 18 of the bushing.
- the expanding tool 28 As the expanding tool 28 is advanced, it coacts with the reduced wall thickness flip extremity 14 of the bushing and expands that part of the bushing outwardly with primary bending taking place at the annular weakened area 16 defined by groove 15.
- the stepped shoulder 22' there shown is considerably thicker in a radial direction than is the shoulder 22 shown in FIGS. 3-5.
- the shoulder 22' and the opening 20 in structural component 19 each have a diameter D 3 which is considerably greater than the outside diameter of the second retaining head 29 formed during the flipping operation.
- a retaining ring 30 having an outside diameter greater than D 3 and an inside diameter at least equal to the diameter D 2 of the flared extremity 18 (FIG.
- thermoplastic material employed in such close tolerance bushings is not critical to the present invention and various commercially available well-known materials can be employed.
- the thermoplastic material comprises nylon (an inherently tough material) with or without additives such as molybdenum disulfide to provide added lubricity and reduced coefficients of friction.
- nylon is an inherently tough material characterized by its durability and long life, it also tends to be somewhat noisy when used in some close tolerance installations such, for example, as seat moutings in automobiles. Consequently, where noise problems are particularly objectionable, it is preferred to use polyethylene which is characterized by its non-squeak characteristics.
- thermoplastic materials such, for example, as polyvinylchloride, Teflon, polycarbonates, acetal resins, etc.
- the bushing is to be used in heated environments, it is preferably formed of a heat resistant nylon or a heat resistant urethane material.
- the particular thermoplastic material selected be characterized by both elasticity and ductility which permit progressive deformation of the material in the setting operation until a point is reached where a self-impelled elastic recoil action occurs to turn the flipped extremity 14 of the device inside out so as to provide a tight, close tolerance, snug fitting, permanent bushing installation.
- the range of thermoplastic materials having various durometers and which are suitable for use in self-retaining bushings will be significantly increased.
